7P Three Phase Four Wire Din-rail LCD Display Energy Meterr

The meter connection should be selected in accordance with the overload current device in the circuit, the performance of the circuit-breaker, and the relevant local codes.

In the selection of external air switches or circuit breakers, should be in accordance with local. standards and the current construction of the electricity design, and should be outside the air switch or circuit breaker installed in the meter line, use it as a meter power equipment , and pay attention to the place near the meter in order to facilitate the operation.

In the choice of external fuses, fuses as overload protection devices, should be in accordance with local standards and the current construction of the power design, and should be external fuse, fuse in the table into the table line used as a broken meter Electrical equipment, and pay attention to the place near the meter in order to facilitate the operation.

The meter can be installed either directly in the indoor or waterproof case can be installed in the outdoors.

The specific situation according to the relevant local standards

Please install a padlock or similar device to prevent stealing

This watch must be installed on a fireproof wall.

This watch must be installed in a ventilated and dry place.

Be sure to place the watch in a protective case when it is necessary to install the meter in a location that is dusty or dangerous.

The Meter must be tested, stamped and affixed with a qualified sign before installation place this watch in a convenient location for reading

When the meter installed in the interference of many places, such as multi-mined areas, welding machines, converters, please install anti-jamming device

After the installation is complete, please close the meter to prevent stealing

Please follow the wiring diagram below to connect the meter circuit

This product is available in two wiring options (please note that you purchase the instrument wiring type)

The meter has RS485 remote meter reading function, the meter has the following optional features, (the meter can be with power failure, can be with back light, with a switch output, can display the total power, current, voltage, power, power factor , Frequency, etc.) can accurately measure the active energy.Energy meter using large-screen LCD display.

The three-phase four-wire power meter also has a pulse output independent of the internal circuit. The 17-terminal (terminal 4) of the meter is connected to the positive terminal and the negative terminal

of the terminal 18 is connected to the negative terminal of the 18th. The voltage is 5 ~ 27V DC with a maximum current of 27 mA DC. U type Meter 15 (A) is the positive side of RS485, 16 (B) is the negative RS485 terminal.

The energy meter through its RS485 interface to achieve long-range copy of the table, such as electricity energy data. And through its infrared communication interface with a handheld computer to achieve close-up copy of the table of energy data. Encoding format, parity (even parity) and data transmission (eight data bits, a stop bit) in line with MODBUS-RTU standards. Communication baud rate defaults to 1200bps,2400bps,4800bps,9600bps.

New type with Modbus communication function Meter .3x220 / 380VReference voltage (Un) ，≤ 0.004bStarting current ，30Imax 0.01s Tolerance overload current ，Working frequency is 50Hz ± 10%，with 400imp 1600imph Pulse constant.
